Device for bridging the joint between two parts of roof and method for testing its tightness
Реферат: ABSTRACT OF THE DISCLOSURE: An expansion joint unit is made up of two side sections and an expansion joint strip made of a resilient material and bridging the joint with its center portion. The edge portions of the expansion joint strip are vulcanized to the side sections. Disposed between the expansion joint strip and the side portions are separating strips defining chambers which are inflatable by way of openings. According to the method, a pump and/or pressure guage is connected to the openings for supplying compressed air to the closed space and the pressure is observed over a period of time. A drop in pressure is a clear indication of a defective expansion joint element.
